Subterranean are very social termites travel that live in colonies. They travel in tunnels, often called “mud tubes or mud galleries,” in order to reach food sources. These mud galleries allow them to come above ground and be protected from predators, sun burn and dehydration. Underground tunnels from a central colony can extend in any direction as far as 100 yards in search for food. Subterranean termites eat wood and cellulose 24 hours a day, seven days a week. When a nest becomes mature and well established, thousands of swarmers will go off to start new colonies. They typically swarm in the Spring months or after a rain.


Subterranean termites are relatively secretive in their presence. They enter buildings through expansion joints, cracks in concrete, plumbing traps, tunnel up foundations and piers. Mud galleries are used to provide protection for subterranean termites to travel and forage food. If mud tubes are disturbed, the termites will abandon the area and move onto a new location in the building.


Subterranean termites are the most destructive termite species. The repairs can be very costly especially if you need to remove load bearing walls or structural timbers in the roof. Homeowner’s Insurance does not cover termite damage to structural timbers. They rapidly eat out the internal sections of timbers. Over time, the damage can collapse a building entirely.

Subterranean Termite Prevention

Subterranean termites form new colonies by gaining access to enter buildings through expansion joints, cracks in concrete, plumbing traps, tunnel up foundations and piers. They can be deterred by making sure the structure does not provide a food source to allow them access to the structure. Exposed wood timbers such as in unfinished attics, garages, and sub-areas can be treated with Bora-Care to form a barrier and prevent termites from entering the wood. Make sure all cracks and crevices are sealed with caulking. Firewood and scrap wood should be stored at least 20 feet from the home. The control of subterranean termites can be improved significantly by having annual termite inspections so that any new infestations can be caught early and treated.
